SPECIFICATION forming` part f Letters Patent No. 723,535, dated March 24, 1903.
Application filed March 8, 1902. Serial No. 97,342. iliio modelo To all whom t may concern:
Be it known that I, FRIEDRICH KUGLER, a subject of the Emperor of Germany, residing at Frauenfeld, Switzerland, have invented new and useful Improvements in Book-StitchingD Machines, of which the following is a specification.
This invention relates to means in bookstitching machines for bringing the ends of lo the stitching-thread to the inner side of the fold after the formation of the knot. The apparatus is provided with tongswhich serve for clamping the thread and in conjunction with the gripping device that holds one end I5 of the stitching-thread move the thread after it has been cut and the knot has been formed in such a way that the free end of the thread projecting from the knot above the stitched' sheets is brought to the inner side of the fold.
zo An exampleof apparatus according to this invention is shown in the accompanying drawings, in which- 'A Figure 1 is a section on the line C D of Fig.
2. Fig. 2 is a plan, and Fig. 3 a rear elevation. Fig. 4 is a section on the line A B of Fig. 2. Fig. 5 is a detail view, and Figs. 6
and 7 show to a larger scale two different positions of the part that serves for holdingvthe stitching-thread and of the gripping device.
3o Fig. 8 is a diagrammatic view showing the relation of my improvement to the stitching and knotting mechanism of one type of book stitching machine.
The book-stitching machine to which the present improvements are adapted is constructed, for example, in accordance with the specification of my United States Patent No. 705,363, of July 22, 1902. is referred to for details of the construction 4o and mode of operation of this book-stitching machine. v
On the pressure-plate 2,.which is mounted on'the slide-plate 1, there is mounted in a recess 5 a pair of 'tongs 4, with two spring-arms, on one of which are mounted two projections 6, that are adapted to enter in corresponding depressions 7 on the other arm when the two arms are pressed together. The tongs 4 are pivoted ou a lever S, formed with a slot 10,
This specificationV engaging with a pin 24, which is mounted on go one arm 9 of the'shears A slot on this arm 'likewise engages a pin mounted on a bar 11, which is adapted to slide in a recess in the pressure-plate 2. This bar carries two upwardly-projecting stops 13 and 14, against 55 which an arm 16 (shown diagrammatically in Fig. 8) can strike alternately, so as to effect a to-and-fro movement of the bar 11. The bar I1 is formed on one side with a notch 12, against which bears the pin 15 of a bar 17, 6o which tends under the influence of a spring 18 to Vpress together the arms of the tongs 4, against one of which it bears. During the stitching process the tongs 4 are open, and the stitching-thread is placed between the two arms and bears on the projections 6, which hold the stitching-thread in the proper position, so that it is clamped when the tongs are closed. After the formation of `the knotA the arm 16 acts on the abutment 14 7o -and causesv the slide 11 to move to the right.
Fig. 2.` At the same time the pin 15 slides into the notch 12, and the' bar 17 presses under the inuence of the spring 18 the arms of the tongs 4 together, so that when the projec- 7 5 tions 6 have entered the depressions 7 the stitching-thread is clamped somewhat in front of the loop 20. At this moment the formation of theknot is completed, the knot is drawntight,-andthe end 23 of the thread is 8c cut; The position of the parts at this moment is shown in Fig. 6. The tongs 4 are then moved to the right by the arm 9, whose pin 24vhas passed through the slot lO during the previous operation of the shears and the cutting ofthe thread, and the gripper 21, that holds one* end of the stitching-thread, is moved through the same distance to the left, whereby the stitching-thread .19 is moved in such a wa-y that the knot istransferred from 9o the position shown in Fig. 6 to that shown in Fig. 7, and the clit end 23 of the stitchingthread projecting on the upper side of the sheets 22 to be stitched lies on the lower side of the sheets or on the inner side of the fold. When the bar 11 moves farther to the right, the pin l5 finally leaves the -notch and the arms of the tongs 4 open. During the movement of the arm 16 in the opposite direction the parts are returned to their initial positions.
l. In a book-stitching machine, the combination, with the stitching,knotting and severing mechanism, of means adapted to engage the thread and to move the same longitudinally to an extent sufficient to bring the knot to the inner side of the fold.
2. In a book-stitching machine, the combination with the stitching, knotting and severing mechanism, of means adapted to frictionally engage the thread and to move the same longitudinally to an extent sufeient to bring the knot and severed ends to the inner side of the fold.
3. In a book-stitching machine, the combination,with the stitching, knotting and severing mechanism, of clamping means adapted to engage the thread forming the stitch, and means adapted to actnate the clamping means longitudinally whereby the knot will be brought to the inner side of the fold.
4. In a book-stitching machine, the combination,with the stitching, knottingand severing mechanism, of a clamp adapted to frictionally engage the thread, a gripper adapted to hold one of the ends of the thread, means operating to move said clamp and gripper longitudinally whereby the knot and severed ends will be brought to the inner side of the fold.
5. In a book-stitching machine, the combination, with the stitching, knotting and severing mechanism, ofa clamp adapted to frictionally engage the thread on one side of the stitch, a gripper adapted to hold one of the ends of the thread on the opposite side of the stitch, and means operating to move said clamp and gripper longitudinally whereby the knot and severed ends will be brought to the innerl side of the fold.
6. In a book-stitching machine, the combination,with the stitching, knotting and severing mechanism, of tongs adapted to frictionally engage the thread on one side of the stitch, a gripper adapted to hold one end of the thread on the other side ot the stitch, a spring serving to hold the arms of the tongs in engagement with the thread, a slidable -bar 'actuated by the stitching mechanism and serving to throw said spring into and out of engagement with the tongs, a lever actuated by said bar and operating to move said tongs longitudinally, means operating simultaneously to move the gripper longitudinally as the slidable bar is actuated, whereby the tongs and gripper will engage the thread and draw the same longitudinally, bringing the knotted ends of the same upon the inner side of the fold.
7. In a book-stitching machine, the combination, with the stitching and knottin g mechanism, of a slidable bar adapted to be reciprocated by the stitching mechanism, a longitudinally-movable clamping device having two arms lying on opposite sides of the thread, a spring-controlled bar bearing against the arms of said clamping device and adapted to be actuated by the slidable bar, an arm connectedwith the slidable bar and serving to operate the thread-severing mechanism, and a slotted bar connected with the arm at one end and to the clamping device at the other end, whereby after the forming of the knot the thread will be severed and the gripping device caused to draw the thread longitudinally so as to bring the knot and severed ends to the inner side of the fold. i
8. In a book-stitching machine, the combination, with the stitching and knotting mechanism, of a slidable bar adapted to be reciprocated by the stitching mechanism, a longitudinally-movable clamping device having two arms lying on opposite sides of the thread, a spring-controlled bar against the arms of said clamping device and adapted to be actuated longitudinally by the slidable bar, an arm connected with the slidable bar and serving to operate the thread-severing mechanism, a slidable bar connected at its slotted end with the arm and at the other end to the clamping device,l gripping means adapted to hold the end of the thread during the knotting operation, and means adapted to actuate such gripping means longitudinallyat the same time with the longitudinal movement of the clamping device, whereby after the forming of the knot the thread will be severed and that portion of the thread forming the stitch will be moved longitudinally to an extent sufficient to bring the knot and severed ends to the inner side of the fold.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
FRIEDRICH KUGLER.
